• A Postman API and a Codepen REST API test app are used to send/receive data.

📶 Technologies

• multer v1 is the middleware used for uploading files.
• socket.io v2 is added for real-time event-based communications.
• graphql v14 is added, a query language for APIs.
• bcrypt v2 library used to hash passwords.
• mongoose v5 object modelling for node.js.
• VS Extension Thunder client REST Client for Testing APIs
• Codepen 'REST API test' used to test the app.

💾 Setup

• Create MongoDB Atlas Cloud database (or local installed MongoDB database) and add user access/database credentials to a new .env file - see .env.example - referred to in app.js.
• Add IP address to MongoDB Atlas Network Access whitelist. Or simply whitelist all (IP address 0.0.0.0/0).
• Run npm start for a dev server. Navigate to http://localhost:8080/. The app will automatically reload if you change any of the source files.

💻 Code Examples

• getPosts method from controllers\feed.js

exports.getPosts = async (req, res, next) => {
  const currentPage = req.query.page || 1;
  const perPage = 2;
  try {
    const totalItems = await Post.find().countDocuments();
    const posts = await Post.find()
      .populate('creator')
      .sort({ createdAt: -1 })
      .skip((currentPage - 1) * perPage)
      .limit(perPage);

        // return a response with json data
    res.status(200).json({
      message: 'Fetched posts successfully.',
      posts: posts,
      totalItems: totalItems
    });
  } catch (err) {
    if (!err.statusCode) {
      err.statusCode = 500;
    }
    next(err);
  }
};

🆒 Features

• None

📋 Status & To-Do List

• Status: Part complete & working, Connects to database but nothing viewed on localhost:8080. localhost:8080/graphql works
• To-Do: Complete code or replace. Also requires more commenting and screen shots.
